From the description on the ghacks.net site above, it appears that LastPass is intended to work among other machines on the network:
It is for example possible to access the passwords on other computer systems without having to carry them around on storage devices like USB sticks. And since Last Pass is not only compatible with Internet Explorer it comes also handy for users who work with web browsers like Firefox. It is basically possible to share passwords and other data between Internet Explorer and Firefox this way.
You could also send an e-mail to Bill with a screen copy of the alert (Bill really likes screenies

) and find out if he knows anything about it. Make it quick though 'cause he'll be leaving for the MVP Summit early next week. (
